By the Skins of her Suits
As Starlight Glimmer stared down at the human's museum, she thought of the many ways life liked to fuck with her.
Curveball after curveball defined her life as of late, and she was fine with most of them.
Befriending the Lord of Chaos while learning to run Twilight's School of Friendship wasn't something she'd ever do in life, but it was fun regardless.
Dethroning a Changeling Queen and helping to save an entire species from perpetual starvation wasn't usually on a pony's bucket list, but she could tick that off with a smile.
Defeating a pegasus filly who was trying to drain all of the magic in the world using her as a conduit for a worldwide spell? Okay, well, she didn't actually beat her but she taught the students who did, so she thought some partial credit was due.
Having to cross dimensions to steal ancient magical artifacts from an alien museum after her marefriend tossed them through a gaudy mirror portal as a means of a tantrum for not bringing her to Hayburger for her anniversary?
Knowing Trixie, this was actually something that she'd thankfully had prepared for.
Standing atop a roof in the middle of the night, Starlight's new human body was clad in a black skin-tight bodysuit, the polymer substance clinging to her voluptuous frame desperately with every constricting motion. Through the black fibers, she could see the bare skin of her human body beneath it, The combined tightness of the suit and the heat sweltering underneath left it damp, and the traced shapes of her nipples stuck out against the cold of the night.
"Ugh, I hate this thing," she said, tugging at the sleeve pinching her wrist. "If I could use most of my spells without having to wear a bunch of magical fibers, we could have left already. At least this human body seems to have matched my actual age this time, would have sucked to have the suit fall off entirely because it wasn't tight enough and not have magic at all."
"Um, Starry?" Trixie said. "Trixie might need some help."
"Yes, Tri- oh, what the fuck!?" Starlight said, turning to face her lover.
Trixie, the lover in question, the best thing to walk into Starlight's life, was currently struggling to move under the combined weight of several skin-tight polymer suits overlapping one another.
"Trixie may have taken a few too many precautions," she said, laughing nervously.
"Yeah, I can see that! How did this happen!? Twilight only gave us the two suits to use, where did the others come from!?"
"W-well, Trixie paid attention to what she said this time!" she said, struggling to move her arms in an attempt to accentuate her point with physical motions. "Trixie knew that our magic wouldn't be usable without a conduit! With human bodies having no horns, we'd be useless! Trixie was afraid that her magic wouldn't be helpful unless she had more suits to have easier access to her magic!"
"So I assume you also missed the part where Twilight said that we only needed the one layer because the suit's fibers lose a significant amount of power during spellcasting and so laying on too many layers would act as a wall that's incapable of outputting any spells?"
A few moments of silence passed as Trixie squeaked about in her layers.
"Mmmmmmayyybeeeee?" she said, smiling weakly.
Starlight's palms became intimate with her face as she expressed how done she was with the situation.
"Alright, so I'm guessing Plan A is officially off the table, considering you can't cast a thing under all of that. So, I'm going to just phase through the walls, run in, grab the amulet, and run out. You just go downstairs and wait for me at the portal, alright?"
"I mean, do we have to leave immediately?"
"We're probably going to be chased by cops, so yes, absolutely."
"Then can we hold off on the heist for a bit? Trixie's only ever heard of descriptions of these 'human' bodies, and they definitely don't do justice to how they truly feel," she said, running a hand down her thighs.
"Can you even feel anything under... how many layers did you put on?"
"Fifteen," Trixie said.
"Oh my Celestia, how are you even breathing?"
"Slowly and carefully, like how Trixie wishes you to peel her out of these," Trixie said in a sultry tone, half lidded eyes glancing at Starlight.
Starlight deadpanned at the mare.
"Come on, Starlight, have you looked yourself in a mirror while here? You're the sexiest mare in every world, and these suits definitely help accentuate the fact with a very bold look."
"Well... I'll admit, the tightness is starting to get me a bit moist," Starlight said, running a hand down between her thighs.
"Exactly! And think, I can't get myself out of these without any help!" Trixie said, feigning despair. "If only some strong, sexy mare would just... rip it all off of me like a wild beast in heat!"
"Oh, I'm definitely going to rut you something fierce when we're done here," Starlight said, licking her lips. "But for now, I have to make sure that the Alicorn Amulet doesn't end up causing another ERP."
"I'm sorry, ERP? What is that, some kind of slang?"
"Yeah, the mare that lives here, Sunset, made it with her friends. It's shorthoof for 'Equestria Related Problem', usually meant for something that Starswirl the Bearded sent over here instead of dealing with himself. Twilight passed along that if she has to end her vacation early to deal with another relic being thrown into her plane of existence like it's a multiversal trash can, she'd have our teats. And not in a fun way!" Starlight said, pointing a finger pointedly. "If you'll excuse me," she said, wrapping herself in magic.
Starlight flew down through the building's roof while Trixie squeaked about in her layers upon layers of suits, sweat dribbling down her face as she combed her hair back.
"Trixie needs to pee."
"Waste of my fucking Sunday," Flash Sentry said as he idly strummed his guitar.
Sitting alone in the museum's security room left him with nothing to do but watch empty camera feeds for hours on end. While he was grateful for the easy income, he was still bored out of his mind without any outside stimulus. Resorting to just playing songs all night, he'd run out of anything to play, and found his fingers sore. Looking up, he checked the camera focused on the strange winged-horse amulet thing again, to see it still sitting there, glaring at the camera with ill intent.
"Meh," he mused, putting down his instrument. "Already told Sunset about it, not much else I can do until whoever's taking it shows up."
He'd of course been made privy to the plan, given he'd had a hand formulating it. So long as there were working cameras, Sunset's friends would be easily picked out and arrested for stealing property. Turning off the cameras and erasing the evidence would help immensely more than trying to convince a courtroom that stealing a horse-land artifact from another dimension was genuinely an act of goodwill, and not at all a heist.
Just as he was about to dig into a bag of carrots, he caught sight of something big. Two something bigs, actually, both of whom could rival watermelons and were nearly ripping open the skintight black suit that the flying girl was wearing. Flash's eyes glued to the screen as he watched her glow in a pale blue light, a light that made the barely visible bodysuit turn even less visible, and showed off her delicious curves as she reached into the glass case as if it weren't there, plucking out the artifact and flying off through the ceiling.
It took Flash several seconds for his brain to catch up, what with the blood suddenly flowing away from it in a rapid ingress. He quickly opened the program for the security footage and isolated the last ten seconds, cropping it out and sending it to his phone before deleting the source. He reached into the security desk and pulled out a bottle of lotion as he opened the footage on his phone's video player.
Trixie idly kicked her legs about in the air, waiting for Starlight to come flying back. Her hands trailed down to explore herself, only now able to spend time admiring the wonderful body she'd been given in this other world. Humans were an alien concept to her, and none of the descriptions or anatomy lessons Twilight gave them did justice to what she witnessed. The grace and poise of her struts, the volume of her teats sweltering twofold, the strange yet alluring redistribution of her assets to be more varied as opposed to centralized in the crotch, it was all fascinating to experience.
Of course, Starlight's natural beauty evolved as well, overshadowing even the great and powerful endowments that Trixie had been gifted. Trixie was always a bit envious of Starlight, having both the endowments of the mind and the material over Trixie, being a brilliant spell caster as well as a gorgeous mare, and it was hot as fuck. Trixie always held herself in high regards, such was the price for being a showmare with an image to maintain, but Starlight embodied everything Trixie's stage presence said it was, and then some. Just thinking of the powerful, beautiful mare, strutting about in such a tight suit, drove Trixie further and further down until she reached-
"Hey pretty mare," Starlight whispered.
Straddling atop Trixie, Starlight appeared from nowhere, her magic fizzling through her bodysuit like an erotic lightshow. Starlight licked her lips as her magic pulled at the suit's fringes, ripping it open and freeing the human breasts. The sweat drenched mammaries smacked Trixie in the face, and stuck as she was, she made no effort to fight back as the humanized unicorn smothered her in titflesh.
"Yeah, that's right, you love this new form, don't you?" Starlight said, dominant in her tone.
Her hand reached down between Trixie's legs, and even through dozens of layers, Trixie could feel the magical digits known as "fingers" prod at her puffy lips. The nailed edges of Starlight's fingers lit brightly with magic, whirring with power as they cut their way through the first layer of the suit. As the fabric retracted and ripped, Trixie moaned into the mounds of breasts drowning her, the relief of freedom finally edging closer as layer after layer was stripped from her pussy.
"That's right, just lay back... and... relaaax~," Starlight whispered as she freed her girlfriend's pussy to the open air.
Unable to contain herself, Trixie screamed as she let herself loose.
Starlight flew up to the rooftop and found Trixie laying on the ground, panting heavily as sweat poured out of the neckline, drenching her hair.
"Ah, thank Faust, an angel here to take me to elysium!" Trixie said, reaching limply for Starlight.
"Of course you're overheating," Starlight said, pinching the bridge of her nose. "Come on, let's go home."
"But... but, sexy body su-u-uuuits!" Trixie whined.
"We can come back through the portal another time for sweaty bodysuit monkey sex, alright?" Starlight said for the first, and unfortunately not last, time in her life.
"UGAAH!" Trixie screamed, flailing against the tightness of her suits.
"Alright, champ, let's go," Starlight said, picking Trixie up out of her puddle.
It was only then that Starlight realized two things.
Most of this wasn't sweat.
And they were going to need way more bleach at Twilight's castle.
